FRONT Ron FOR DOUBLE 'SLIPS.

SPECIFICATION forming part of Letters Patent No. 509,128, dated November21, 1893. Application filed March 27, 1893- $erial No. 467,6 82 4 (Nomodel.)

To all whom it mag concern.-

Be it known that I, ARTHUR H. JOHNSON, of Rahway, in the county of Unionand State of New Jersey, have invented a new and useful Improvement inFront Rods for Double Slips, of which the following is a specification.

My invention relates to an improvement in front rods for double slips inwhich provision is made for holding the tongues of the movable switchrails which are located intermediate of the inner rails of the crossingtracks, positively in adjustment snugly against one or the other of saidinner rails of the crossing tracks to prevent any liability of theflange of the car wheel entering between the end of the tongue and therail and thereby throwing the train from the track.

Another object is to provide one continuous front rod which will lookall four tongues of a double slip switch two at a time securely againsttheir respective stock rails.

A practical embodiment of my invention is represented in theaccompanying drawings in which- Figure 1 is a top plan view of a part ofa railway track crossing, showing the position of the front rod as inpractical use. Fig. 2 is a view of the front rod in side elevation on anenlarged scale, showing the rails' in cross section. Fig. 3 is a topplan view of a portion of the front rod, showing the holding lugs orabutments in position thereon, and Fig. 4. is a view of a modified form.

The stationary rails of the two tracks are denoted by A, A and B,B', theouter rails of the two tracks being respectively A and B and the innerrails A and B. The tongues of the movable switch rails are denoted by aand a, and b and 1), corresponding to the rails A, A and B, B which thetongues are intended respectively to engage. The tongues a and a areconnected as usual by a series of braces 0 extending at intervalsbetween them, and the tongues 19, b are in like manner connected by aseries of braces G. The front rod is denoted as a whole byD and extendstransversely across the tracks at the points of the several tongues andis intended to lock the tongues, for the time being, in

contact with the rails toward which they are pressed. To this end, thefront rod is provided with suitable abutments thereon arranged to pressagainst the tongues on the sides opposite the rails against which thetongues are to be forced, and the rod is locked in position by theordinary bolt or plunger 19*.

My present invention relatesmore particularly to the abutments E and Eadapted to engage the inner tongues a and b to hold them securelyagainst their respective rails A and B. The particular form of abutmentwhich I find it desirable to employ consists in a flat bearing piecewhich may be secured to the'front rod by a bolt e and which is providedwith an overlapping lip 6' adapted to reach over the flange of thetongue and rest with its free end against the face of the tongue. Theend of the overlapping lip e which bears against the side of the tongueis made slightly curved, as denoted at 6 for the purpose of permittingthe slight relative change in position of the tongue relative to the lipas it is swung toward and away from one of the rails, and at the sametime causes the lip to bear at all times against the tongue to preventany springing of the tongue apart from the side of the rail to admit ofthe entrance of the flange of a wheel between it and the rail.

In the form shown in Fig. 4:, the bearing pieces E, E are secured to thetongues a, b and bear at their inner ends upon a lug d on the front rodD. It is obvious that the two pieces E, E, might be formed integral andsecured to the front rod D and also that the abutments might be made asa part of the front rod.

What I claim is- 1. The combination with the tongues of a double slipswitch, of a single continuous front rod, and abutments, whereby as therod is operated all the tongues are locked, two at a time, against theirrespective rails, substan tially as set forth.

2. The combination with the inner swinging tongues, of a double slip, ofa front rod havingabutmentsthereon intermediate of the said innertongues forholding the tongues firmly against their respective rails asthe ends bearing against the sides of the tongues, front rod isthrown inone or the other direcsubstantially as set forth. tion, substantially asset forth. 4

3. The combination with the inner tongues ARTHUR JOHNSON 5 of a doubleslip, of a front rod provided with Witnesses:

abutments thereon projecting over the base FREDK. HAYNES, flanges of thetongues and having rounded IRENE B. DECKER.
